Exclamation Re: Renault Laguna II - Phase 1 - Engines - Average MPG from 1.9 DCi Engine

well.......the cheapie chip is still going strong!!

as time has gone on im now up to 53.3mpg AROUND TOWN!!

the chip seems to have moved all my power lower down the rev range, the turbo now spins up just before 2krpm (before the chip turbo spun up @ about 2.5krms)

the only time my car now goes over 2.5krms is when i pass 80mph, but it will just as easily chug along @ 30mph in 6th gear.... with 0 shuddering (impossible before chip)


so yeah........ this engine CAN BE the nuts!!!!

I drive from Hannover in Germany to the ferry at Amsterdam and back about 15 times a year in a 2001 mk2 120 1.9 and always average about 55mpg at 80+ mph 145000 on the clock

No definately wrong. With your style of Driving I get high 40s. When towing a large trailer (6'X4'X6' high), car and trailer fully loaded at 70mph on the French Motorways I get 34ish, and 39ish when empty. Injector stuck perhaps or wrong ECU ?

Re: Renault Laguna II - Phase 1 - Engines - Average MPG from 1.9 DCi Engine

I changed my oil to renaults recommended Elf Evolution SXR 5w-40 oil . For a period of 10 minutes my mpg went up to 88!!!!! Seriously, 88!!

Then it went down to a modest 56.5 but it did stick in the 60s for a while.
